shutdown -p should work. You'll need to be root over the network, of course.

shutdown -p will only show up in the Console or Terminal (if it's
running).  Since there is no guarantee users will be running Terminal
or Console a "Broadcast.app" (or something similar) would be nice.
"ShellPanel" can pop open a window with an Alert message in it but if
you want to run it as root (so everyone will see it) I believe the
Public Window Server will have to be open on each station.  This is a
no-no for security reasons.  Anyone have a workaround?  Can root open
the Public Window Server on a station just long enough to broadcast a
message then close it (or leave it in the state it was in)?

Thanks,
Steve

No, shutdown -p doesn't power the machine down. You have to
'shutdown -h -p', to do the job, the manpage is not quite clear about
this.

[This answer for 2.x systems; not verified for 3.0]

You know the "Printing" panel that pops up when your NeXT Laser
Printer runs out of paper?  That's done by a handy little program
called /usr/lib/NextPrinter/Inform.  It turns out that Inform can
display any message of your choosing:

	/usr/lib/NextPrinter/Inform "I hate recycled toner cartridges"

You can also change the text displayed on the "OK" button:

	/usr/lib/NextPrinter/Inform -b1 Extinguish "Fuser assembly on fire"

What it doesn't let you do is change the printer icon or the
"Printing" title, which is too bad, since NeXTSTEP could use
a general-purpose notification service.  (Hmm... you can probably
replace the "PrinterAlert" nib section with whatever you want.)

Oh yeah: if run by root, Inform will work even without Public
Window Server enabled.

You sure can, I just did it in about 25 seconds... makes a great app
to pop up on all the machines in the lab when there is going to be a
system shutdown!
